3.3TT How are Stinger owners cleaning their valves on their GDI engines?

Anyone reading this thread that was sold the same bs from the dealer. Yes, carbon deposits on the intake valves is a problem on DI motors regardless or manufacturer because the fuel detergents dont touch the top side of the valves and therefore do not have a chance to clean the oil deposits due to the PCV system. Prevent the oil from entering your intake track and you by and large prevent carbon deposits from forming on the top side of your intake valves hence the importance of an oil catch can. WMI also cleans the intake downstream from the port it is injected from. If you take the necessary precautions you should not need to clean your intake valves period which is what this entire thread is about.

I think it is worth mentioning that that OCC’s are not 100% efficient. Also, don’t forget that the EGR system contributes to the crap on the back of your intake valve. After experiencing issues with only using GDI, some car manufacturers have switched to using a combination of port and GDI schemes to address the gunk that builds up when only GDI induction is used. I use the Mann Provent 200 OCC with good results, but the intake valves will still need servicing at some point.

Correct.

I am located in Europe, probably the price I've spent won't help much. It's about 320 euro.

Last time I checked, it was 1.2 dollars per Euro, using that ratio, it would be $384. Wonder what the labor rate would be compared to the U.S.?
